Folks
Request a review of the following Steps for Conversion of NON RAC
Database to RAC using Mounted Filesystems.
Am NOT able to find the same in the Oracle 10g Documentation
Configuration
Solaris 10 , Oracle 10.2
NON-RAC Database existing on UFS
RAC Database to exist on Veritas SFRAC ver 5
Qs How will the names (with paths) for the Redologfiles of the 2nd
instance be specified? Is it's creation to be Coupled with Step 4 below?
Any Links, Docs on Conversion will help.
Thanks indeed
STEPS - For 2 node / instance RAC
1. In the initRACOL1.ora Set the following parameter (1 Time) in
addition to the required RAC parameters mentioned below in Appendix
_no_recovery_through_resetlogs=TRUE
2. RE-Create the Controlfile
"startup nomount" & Run the Trace SQL file for RE-Creating the
Controlfile
3. Add the 2nd thread
SQL>ALTER DATABASE ENABLE PUBLIC THREAD 2;
4. Remove the following from initRACOL1.ora
_no_recovery_through_resetlogs=TRUE
